one of his favorites, zac brown band, could always be heard pumping out from his truck going down the street. just the thought of that makes me smile. one of their songs goes "i got my toes in the water, ass in the sand, not a worry in the world, a cold beer in my hand, life is good today, life is good today." life is good because our family has 27 years of memories with sean. he will live in our family and hopefully yours forever. so whether you called him hard cop, bag of donuts, or his boston p.d. covert called him, to our family he was seanie. live long like he would. big smiles, big heart, big service, all love. we know that we'll see him again. and he'll have that big grin and a hug for all of us. officer sean collier, we love you. [ applause ] >> thank you, andrew, both for your words and having shared your brother with those of us at m.i.t. it is an honor to have welcomed him into our family. it is my privilege now to introduce the senior senator from massachusetts elizabeth warr warren. >> we'll have more of this memorial service in just a moment. stion: how old is the oldest
